Most Efficient Way to Invoke Methods at Runtime with a Specific Annotation

I have a class A with a bunch of methods I have annotated the same with unique Annotations. I want to invoke the method at runtime given the specific annotation. Also, I might have to pass parameters as well.

public class XYZAccessor(){
    @CustomAnnotation(id="methodAIdentifier")
    public String methodA(){
        return "A";
    }
    @CustomAnnotation(id="methodBIdentifier")
    public String methodB(){
        return "B";
    }
    @CustomAnnotation(id="methodCIdentifier")
    public int methodC(int param){
        return (5+param);
    }
}

Given the string "methodAIdentifier", I would like to invoke XYZAccessor.methodA();

I have seen these approaches for the same.

1) Java Reflection: XYZAccessor.getClass.getMethods.getAnnotations() Iterate through that and find the specific method and invoke it.

2) Google Reflections: These have javaassist and guava as a dependancy. Use their framework Class.getMethodAnnotatedWith("methodAIdentifier")

3) AspectJ: I am not clear on how to use Aspect for this use case. Something like a pointcut and an @Around. Something like Pointcut matching methods with annotated parameters

Which of these approaches is the most efficient and the best approach to this problem?
